Zeglin Lab: Molecular Microbial Ecology @ Kansas State University Biology


Research in the lab centers on microbial ecology, microbial diversity and nutrient cycling processes in streams and soils. Main goals include the integration of methods on both microbial and ecosystem scales, while addressing questions in managed and 'natural' systems within the context of disturbance and global change.

Ongoing research themes include understanding how grassland management (fire, grazing, fertilization) and drought legacies affect soil microbial community structure and C and N cycling functions, the microbial mechanisms underlying linked C and N biogeochemistry, concurrent development of soil organic matter and microbial communities on fresh parent material (volcanic ash), the hydrologic and nutrient conditions that affect stream microbial diversity and function, and the role of the microbiome in mediating vertebrate development and health. See our "People" and "Projects" pages for more detail.

If you are interested in learning more, get in touch!

We welcome and value perspectives that are outside our individual ranges of familiarity.
We learn from one another, and we know more together.

The belowground plots (BGP) experiment at Konza Prairie: factorial burning and N fertilization treatments since 1986. Guess which plots haven't been burned for 30 years!

A few recent notables:

21 March 2018-
"Long-term fire management history affects N-fertilization sensitivity, but not seasonality, of grassland soil microbial communities" accepted in Soil Biology & Biochemistry. CC's hard work sure was worthwhile!

12 March 2018 -
Reciprocal inoculation experiments: Fertilizer plant effluent vs. Kansas River water nitrification and denitrification potential rates at different N availability levels. The race is on! (pics 1, 2, 3)

8 March 2018-
"Vertical changes of soil microbial properties in claypan soils" accepted in Soil Biology & Biochemistry. Way to go, Jerry!

1 March 2018 -
With support from the NSF-DEB-Ecosystem Science RAPID program, we can really learn something here! Specifically, could the inoculation of the Kansas River with a high-N enriched microbial community affect the N-processing capacity of the ecosystem?

1 February 2018 -
The field season begins early this year... The Burgin Lab and Zeglin Lab are tracking the biogeochemical and microbiological impact of the unanticipated release of fertilizer production waste into the Kansas River.

12 January 2018 -
Science planning meeting, for the new Kansas EPSCOR Microbiomes of Aquatic, Plants and Soils (MAPS) RII Track-1 project, at the Kansas University Biological Station near Lawrence. A supportive team has gathered here, full of excitement to learn more about how Kansas microbes respond to precipitation and land-use change!

... HELLO 2018!

Priscilla presented her new data on "Impacts of prairie land management on nitrous oxide production" at the KSU Research and the State Forum. Should our state legislators learn about rangeland greenhouse gas emission? Good question.

Scouting trip for aquatic sites in Western Kansas with Dr. Burgin and Dr. Sullivan from KU and Dr. Mehl from the Nature Conservancy. Reminiscent of my PhD work in New Mexico, classic intermittent streams in a semi-arid landscape: The Smoky Valley River near Oakley and near Cedar Bluff Reservoir.

Great to visit University of Illinois-Champaign NRES, connect with colleagues, share some new research findings, interact with some promising students, and learn about a new place.

14 Oct 2017 -
Great Plains Limnology Meeting in Columbia, MO: Wonderful to connect and reconnect with local aquatic ecologists, and to be reminded of the importance of water quality in the Midwest US to global environmental health! Janaye did a great job presenting her first poster, discussing how biofilm enzyme activities indicate water quality.

5 Oct 2017 -
Priscilla won "best slides" for her presentation on her graduate research at our EEB Graduate Students on Parade event! Way to go!

4 Oct 2017 -
A new NSF-EPSCoR Track 1 award will support research on microbiomes in aquatic, plant and soil habitats across the state of Kansas - Our "MAPS" project begins...

23 Sept 2017-
Priscilla collected her last soil sampling for nitrification/denitrifcation potentials and nitrifier/denitrifier diversity measurement! A solid season of fieldwork is complete.

30 Aug 2017 -
Kasatochi fieldwork success for another year. It's the 9th year post-volcanic eruption: even here, there is life (pics 1, 2).

7-10 Aug 2017 -
ESA was great, a lot of really exciting research across a breadth of scales. Priscilla presented her first poster (thanks for sharing)!

26 July 2017 -
A productive collaboration: Robin's frog development model shows that gut microbiome structure and developmental trajectory is affected by egg inoculum (Integrative and Comparative Biology).

24 July 2017 -
CC defended her Master's Thesis, and of course did a great job! Those 2 years sure went fast, I learned a lot too, incuding that I should take more pictures with my students! Research highlights: cessation of burning increases sensitivity of soil prokaryotes to N addition; fungal communities under woody-encroached prairie still resemble prairie, not forest; seasonal community turnover of native prairie soil microbial communities is undetectable at our site.

Talked to a group of restoration managers from across the Great Plains; really interesting to think about the prairie from different perspectives, thanks Grassland Restoration Network.

Here is a unique new book on an understudied portion of many landscapes: Intermittent and Ephemeral Streams - including a chapter on microbial diversity.

New bison calves on the prairie and a new behavioral observation (new to me): cows defending the young calves in a circle of protection. Normally these animals are totally unconcerned when a vehicle stops along the access road.

14 April 2017 -
The graduate students like me; I think it's because they know I like them too. (Recieved the 2017 Outstanding Graduate Faculty Award from the KSU Biology Graduate Student Association.)
